Investigate the details of RE support in PHP, Tcl, Python, Ruby, JavaScript, Emacs Lisp, Java, and C#. Write a paper that documents, as concisely as possible, the differences among these, using Perl as a reference for comparison. Do a web search for Perl 6, a community-based effort that has been in the works for many years. Write a report that summarizes the changes with respect to Perl 5. What do you think of these changes? If you were in charge of the revision, what would you do differently?
